When leveling an evoker and learning fire breath they have a little obelisk you can click to reset the ability’s cooldown instantly. Would be cool if they implemented a little dueling/pvp hub somewhere with a similar cd-resetting mechanic.
on a tangent, it’d be cool to have some kind of open-world pvp currency that players drop a portion of when killed in warmode (kind of how Stygia worked in the maw). Then in the dueling hub you could wager the currency on duels and buy cool stuff with it
